What is it?

Manuka honey may help prevent infections and promote wound healing when used externally.

Manuka honey can help fight bacterial infections and has been used in dressings to promote wound healing. Methylglyoxal, a major compound in this honey, is thought to be responsible for these effects. In vitro and animal studies also suggest anti-inflammatory and anti-ulcer properties. Small studies in humans suggest its benefits against gingivitis and inflamed nasal sinuses. However, it has not been found to be effective in reducing cancer treatment-related side effects such as inflammation or sores in the mouth or throat. Larger studies are needed.

What are the potential uses and benefits?

  • Wound dressings
    Small studies suggest the value of manuka honey in wound healing.
  • Antibiotics
    Topical use of manuka honey was shown to be effective against bacteria.
  • Diabetes
    Clinical trials are lacking. Excessive use of honey may increase in blood sugar levels.
  • Gastrointestinal tract problems
    Clinical trials have not been able to confirm if manuka honey can improve beneficial bacteria in the gut.
  • Infections
    Several case studies have described manuka honey as being effective to treat wounds that did not respond to standard treatment.
  • Cancer prevention/treatment
    Clinical trials are lacking.
  • Radiation side effects
    Clinical trials did not find any benefit with manuka honey for either radiation-induced oral mucositis or esophagitis, but one study found that it reduced bacterial infections.
  • Oral health
    One small study suggests using manuka honey may help reduce buildup of plaque and gingivitis. Large-scale studies are needed.

What are the side effects?

  • The sugar content in manuka honey may raise the blood glucose level in those with diabetes.
